SPECIFICATION forming part of Letters Patent No. 779,588, dated January10, 1905. Application filed September 19, 1904. vSerial No. 224,990.

To ir/ZZ whom t may concern:

Be it known that I, JosIAH S. CUsHING, of Norwood, county of Norfolk,State of Massachusetts, have invented an Improvement in Wheel-Tires, ofwhich the following description, in connection with the accompanyingdrawings, is a specification, like-characters on the drawingsrepresenting like parts.

This invention relates to wheel-tires especially designed forautomobiles and other vehicles requiring' very durable yet moderatelyvresilient tires. I The wheel-tire embodying this invention comprises,essentially, one or more circularlyformed tubular layers, eachcomprising a plurality of helical springs, which are connected together,and an outer tubular wrapper, preferably elastic, inclosing said layers.Preferably a central yielding core will be contained within theinnermost tubular layer. The helical springs may be disposed inparallelism and extend transversely around the tire, or they may extendlongitudinally around the tire,

and the helical springs will be interlocked together and alsoadditionally connected together by textile material, which is cementedor otherwise connected thereto.

Figure l shows a transverse section of a portion of a wheel-tireembodying this in vention. Fig. 2 is a plan view of ya. portion of thewheel-tire. Figs. 3, 4, and 5 are details of one of the tubular layers.Fig. 6 is a longitudinal section of a portion of a tire having amodified form of yielding core. Fig. 7 is a transverse section of aportion oi" the tire shown in Fig. 6. Fig. 8 is alongitudinalsection ofa portion of the tire having another modiiied form of yielding core.Fig. 9 is a transverse section of a portion of the tire shown in Fig. 8.Fig. l is a longitudinal section of a portion of the tire having anothermodiiied form of yielding core. Fig. 11 is a transverse section of aportion of the tire shown in Fig. 10.

Referring to Figs. l and 2, a represents the outer tubular wrapper,composed of rubber or other suitable material and constructed in in anysuitable manner, so far as my invention is concerned.

b b represent several concentrically-disposed` circularly-formed tubularlayers which are contained within the outer wrapper a. Each tubularlayer consists of a plurality of helical springs (see Figs. 3 to 5,)disposed in parallelism and interlocked together and also additionallyconnected together by sheets of canvas c c, which latter give to thelayer a smooth exterior iinish. The sheets c c of canvas are attached tothe helical springs by rubber cement, as shown at b2. The tubular layersthus constructed are moderately resilient and very durable.

In case the circularly-formed tubular layers are composed of interlockedhelical springs made up as flat sheets bent or formed into tubular shapewith the edges abutting ltogether extra pieces of canvas b* will bewound around them. As many of these layers will be provided as desired,they being concentrically arranged.

Within the innermost tubular layera yielding core Z is or may beprovided, which will be composedof hemp, as shown in Fig. 1, or it mayconsist of a circular spring of flat metal, as shown in Figs. 6 and 7,or a helical spring of at metal, as shown in Figs. lO and l1, or it maybe composed of a helical spring of wire, as shown in Figs. 8 and 9.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. In a wheel-tire, one or more circularlyformed tubular layerscomprising sheets of textile material and a plurality of helical springsconnected together which are interposed between said sheets of textilematerial and attached thereto, and an outer tubular covering inclosingsaid layers, substantially as described.

2. In a wheel-tire, one or more circularlyformed tubular layerscomprising sheets of textile material and a plurality of interlockedhelical springs connected together which are interposed between saidsheets of textile material and attached thereto, and an outer tubularcovering inclosing said layers, substantially as described.

3. In a wheel-tire, one or more circularlyformed tubular layerscomprising a plurality of helical springs connected together and IOOsheets of canvas between which said springs are placed and to which theyare attached by cement, and an outell tubular covering inclosing saidlayers, substantially as described.

4E. In a wheel-tire, one o11 more circularly- .formed tubular layerscomprising sheets of textile material and a plurality of helical springsconnected together which are interposed between Said sheets of textilematerial I O and attached thereto, an outer tubular eovei-l inginelosing said layers, and a yielding core contained within theinnermost tubular layer, substantially as described.

' In testimony whereof I have signed my name to this specification inthe presence of two sub- I5 Seribing witnesses.
